On-Chip Antennas in SiGe BiCMOS Technology: Challenges, State of the Art and Future Directions

This paper reviews recent works on on-chip antennas utilizing different integration concepts in Silicon-Germanium (SiGe) BiCMOS technologies. Challenges as well as key design parameters of the on-chip antennas are addressed and a novel antenna integration concept based on a micromachining technique is described. The utilization of the on-chip antennas in different applications is also discussed. The integration of the on-chip antennas in the radar transceivers allows for a high miniaturization potential of the sensors. Compact high-resolution radar sensors at frequencies above 100 GHz become feasible and attractive for short range applications.
